CUTTING AND PANNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 570,870, dated November3, 1896.

Application filed June 26,1895. Serial No. 554,171. (No model.)

T0 610% whom it may concern:

Be it known that I, LE GRAND B. DAVID- SON, a citizen of the UnitedStates of America,

residing at Denver, in the county of Arapahoc and State of Colorado,have invented certain new and useful Improvements in Outting and PanningMachines; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to a machine specially designed for use in thepreparation of cereal food, but which may be employed in other relationsof a kindred character. The machine will, however, be described in thisspecification with special reference to its use in the manipulation offood material subsequently to shredding or analogous treatment andpreparatory to baking. Hence this intermediate function consists in thecutting of the shredded or otherwise prepared material into cakes anddropping the cakes upon a pan ready for baking.

The mechanism consists, generally speaking, of a reciprocating box intowhich the material is discharged in layers of uniform thickness from asuitable shredding-machine, (not shown 3) a chain of knives for cuttingthe layers deposited in the box into cakes of uniform size, and acarrier or conveyer for the pan, which is moved beneath the box at rightangles to the reciprocation of the latter, together with suitableconnections whereby the movement of the reciprocating box adjusts andoperates the knives and propels the pansupporting carrier or conveyer,all of which will be fully understood by reference to the accompanyingdrawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a sideelevation of the machine. Fig. 2 is asection taken through the frame on the line 00 00, Fig. 1, lookingtoward the right. In this view the upper part of the knife-belt isremoved. Fig. Sis atop or plan view of the machine, the reciprocatingbox, the knife-belt, and its supporting and actuating mechanism beingremoved.

Allthe detail views are shown on a larger scale than in the general views,where the parts are assembled.

Similar reference-characters indicate corre- 8o spondingparts in theviews.

Let the numeral 5 designate the upright cast-iron frame of the machine,to which are attached the cast-iron arms 6. There are two pairs of thesearms, one pair being attached to each side of the main frame and onopposite sides thereof. Each pair of arms is connected by a brace 7. Thearms 6 support two shafts 8, to which are made fast pulleys 9, connectedby belts 12.

As shown in the drawings, there are two pulleys on each shaft, and thesepulleys are connected by belts 12. It is evident that in place of thepulleys and belts sprocket wheels and chains or other equivalentconstructions 5 may be employed without departing from the spirit of theinvention. This mechanism-as a whole will be termed the carrier orconveyer. Located above the carriermechanism and occupying a position atright angles 10o thereto is the reciprocating box 13,,supported bystationary guides 14. The box and its guides are provided withcounterpart tongues and grooves, whereby the box is permitted to movefreely back and forth. Attached to the bottom of the box is a continuouscogged rack 13. Midway between the sides of this rack is a tongue 13,which forms the guide for the upper extremity of a shaft 15, carrying apinion 16 of less diameter than the space between the two sides of therack and so located as to engage the latter. The attachment of the rackto the bottom of the box forms a shallow, elongated recess of sufficientdepth to receive the gear 16. The tongue 13 terminates at a sufficientdistance from the rack extremities to allow the gear to pass around thetongue at these points as it passes from one side of the rack to theother. By means of the pinion 1G and the rack 13 the box 13 isreciprocated.

The lower extremity of the shaft engages a socket formed in a support 15and has sufficient movement in this socket to allow the shaft aslightoscillation as it moves or passes from one side of the rack to theother. Just above the socket extremity of the shaft is located a fastbevel-gear 17, meshing with another similar gear 18, made fast on ashaft 19. Motion is communicated to this shaft in any suitable mannerfor the purpose of operating the machine.

Located above the box and mounted on wheels 20 is the knife-belt 21,comprisinglinks 21, pins 21, and blades 21 The assembled links comprisetwo parallel chains engaging the extremities of the pins 21. Betweenthese chains, and fast on the pins, are located the knife-blades. Thepins of the knife-belt project outward from the links and engage notchesformed in the peripheries of the wheels 20, fast on shafts 22, whoseextremities are journaled in movable boxes 23, carried by a frame 24 andcontrolled by screws 24. This frame comprises two parallel bars suitablyseparated. To the bottoms of the bars are attached guides 24, havinggrooves, which the extremities of the pins 21 engage. The frame issupported by four vertical posts 25, whose upper extremities engage theside arms of the frame, while their lower extremities are made fast totwo yokes 26. Each of these yokes is hinged to the lower member 27 of atogglejoint, whose upper member 28 is hinged to a hanger 5 on the mainframe. The posts are vertically movable on the frame. Hence theknife-belt frame 24 may be raised and lowered by actuating the toggles.

The two toggle-joints are connected by a bar 29, whose extremities arehinged to corre sponding members of the toggles. One member of thetoggle located farther to the left (referring to Fig. 1) is connectedwith two le vers 30 54 by means of a yoke 31. These two levers arelocated on opposite sides of the machine. The lever 30 is instrumentalin imparting one motion to the toggles, and the lever 30 the reversemovement. The connection whereby this operation of the toggles iseffected will now be described. The lever 30 is fulcrumed at 32,connected with the yoke 31 at 33, and pivoted to an arm 34 at 35. Thearm 34 is provided with a lug 36, which is engaged by a lug 37 on thebox 13, when the arm is suitably adjusted. The normal position of thelug 36, however, is below the path of the lug 37 on the box, for thereason that it is assumed it will be necessary for the box to makeseveral reciprocations beneath the shreddingmachine (not shown) beforethe layer of shredded material will be of the desired thickness. WVhenthis does occur, however, the blades of the knife-belt must be loweredto the cutting position through the instrumentality of the toggles andtheir connections. The raising of the arm 34 to bring its lug 36 intothe path of the lug on the box is effected byawheel 38, carrying a cam38", which engages a block 39, attached to the arm 34, every time thecamwheel rotates. This last-named wheel is made fast on a shaft 40,carrying a centrally-located ratchet-wheel 41, actuated by an arm42,carrying a dog 43. This arm. 42 is pivoted on the shaft 40, and itsupper extremity projects into the path of a cam 44, pivoted to one endof the box 13. This cam is pivoted and so connected with the box thatwhen the latter is travelingin one direction (toward the left, referringto Fig. 1., for instance) the cam swings on its pivot and passes overthe arm 42. When, however,the box is making the reverse movement, thecam maintains its depending position, strikes the arm 42, and gives theratchet-wheel 41 a partial rotation through the medium of the dog 43.The pivoted arm 42 is returned to its upright or normal position by aspring-held rod 45, pivoted to the lower extremity of the arm andconnected with the frame. This rod 45 passes through a stationarycross-head 46, against which the spring 47 bears. As the pawl-arm 42actuates the ratchet-wheel this spring is compressed or placed undertension. Hence as soon as the pawl-arm is released or disengaged fromcontact with the cam 44 the recoil of the spring 47 returns the pawl-armto its normal position. The ratchet-wheel is locked against reversemovement bya dog 48, supported on a stationary cross-piece 49. Hence foreach reciprocation of the box 13 the ratchet-wheel 41, together with thecam-wheel 38, is given a partial turn. In this manner the cam-wheel isrotated, and every time it makes a complete revolution its cam engagesthe block 39 on the arm 34 and raises the latter sufficiently to bringthe lug 36 of the arm in the path of the lug 37 on the box just beforethe box completes its movement toward the left, (referring to Fig. 1.)The movement of the arm 34 should be sufficient to straighten thetoggles by virtue of the connections heretofore described. This movementof the toggles depresses the yokes 26 and lowers the knifebeltsufficiently to bring the pins 21 into the path of driving-lugs 50,pivoted on the box near its extremity farther to the right, (referringto Fig.1.) As the box 13 continues IIO its movement toward the rightafter the clepressing of the knife-belt the latter is moved on itssupporting-wheels 20. During this movement of the knife-belt the blades2-1 thereof are successively carried downward equal to the distancebetween the knifeblades. WVhen the box 13 has reached its limit ofmovement toward the right, (see Fig. 1,) the entire layer of foodmaterial has been cut into cakes, and the knife-belt ceases to move. Thebox then begins its movement in the opposite direction, but thedriving-lu gs 50 turn on their pivots and pass under the belt withoutmoving the latter; Hence as the box 13 moves toward the left it passesaway or from under the knife-belt, and the cakes which are held by theblades of the belt until the box moves away drop to a pan 51,1'esting onthe carriers below, and heretofore described. In order to insure theinstantaneous dropping of the cakes from their position between theknife blades spring-actuated plates 52 (see Fig. .10) are employed. Thesprings which actuate these plates are compressed as long as the box isin position directly beneath. \Vhen, however, the box moves away, therecoil of the springs moves the plates downward suificiently to causethe cakes to drop and clear the belt. These plates 52 may perform theirfunction by gravity alone.

Just before the box 13 reaches its limit of movement toward the left(see Fig. 1) it engages an arm 34, actuates the lever 54, reverses theposition of the toggles, and raises the knife-belt through theinstrumentality of mechanism which will now be described in detail. Thearm 34 is of the same construction as the arm 34, but locatedfon theopposite side of the reciprocating box. Hence it is provided with a lug36 lying in the path of a lug 37 attached to the box, when the arm 34 israised by another cam-wheel 38, fast on the shaft 40. The two cam-wheelsare exactly alike, but so arranged that the cam of one is a step inadvance of the cam of the other, so

to speak. Hence the cam-wheel located directly beneath the arm 34 raisesthis arm during the first movement of the box toward the right after thelowering of the knife-belt to the cutting position. Hence when the boxmakes its next movement toward the left the lug 36 on the arm 34 will bein the path of the lug 37 a on the box. The lugs 36 36 on the arms 34 34should be made adjustable by any suitable contrivance, whereby they maybe so set as to engage the lugs 37 37 on connected with the yoke 31.

lever 30 will be actuated and the lever 54 moved in such a manner as tothrust the the knife-belt by virtue of the construction heretofore setforth.

As shown in the drawings, the elements of the mechanism are soconstructed and arranged that the knife-belt is raised and lowered onceduring a single revolution of the cam-wheels. This arrangement, ofcourse, is based on the assumption that the time necessary to complete asingle revolution of the cam-wheels will also be the time required tocollect a layer of food material in the reciprocating box of sufficientthickness for the cakes into which it is desired to form said material.If, however, it is desired, the wheels 38 may be provided with two ormore cams',-which would efiect the raising and lowering of theknife-belt two or more times dur ing every revolution of the cam-wheels. Hence it is obvious that the time consumed in collecting alayer of food material in the reciprocating box preparatory to cuttingthe same into cakes may be regulated at will.

After each cutting of the layer of food ma terial in the box the cakesare dropped into the pan 51, resting on a carrier underneath, asheretofore described. This pan is made that the pan may be ready toreceive the next batch or row of cakes, it must be shifted a suitabledistance in a direction transverse to the movement of the reciprocatingbox. The mechanism for operating the carrier or con- Veyer upon whichthe pan rests, and whereby the latter is shifted, will now be described.

To the bar 29, connecting the two toggles, is attached a plate56,provided with an elongated aperture, through which protrudes oneextremity of a lever 57, fulcrumed on a bar 58. To the oppositeextremity of this lever is attached a block 59, to which is pivoted oneextremity of a rod 60, the other extremity of the rod being connected toa ratchet-arm 61, pivoted on a shaft 62. One extremity of thisratchet-arm is forked and carries two pawls or dogs 63, which engage aratchetwheel 64, fast on the shaft 62, which carries a bevel-gear 65,meshing with a similar gear 66, fast on the shaft 67, occupying aposition at right angles to the shaft 62. These shafts 62 and 67 aresuitably journaled on a main framework. To the outer extremity of theshaft 67, or the extremity remote from the bevel gear 56, is attached apulley 68, connected by means of a belt 69 with another pulley 70 on oneof the carrier-shafts 8. Hence every time the toggle-bar 29 moves towardthe right, (see Fig. 1,) which movement occurs just after a batch ofcakes'has been discharged into the pan, the lever 57 is actuated in sucha manner as to give the ratchet Hence a single batch" wheel 64 a partialrotation through the instrumentality of the connecting-rod, theratchet-arm, and the dogs. This movement of the ratchet-wheel imparts acorresponding movement to the shafts 62 and 67, and thence to the shaft8, the carrier or conveyer and the pan thereon, by virtue of theconnection set forth.

One of the carrier-shafts 8 is provided with a hand-wheel 71, wherebythe carrier may be adjusted independently of the automatic mechanismdescribed, whenever it may be necessary to adjust the pan or bring itinto the proper position for receiving the first batch of cakes. lVhenproperly adjusted to receive the first batch of cakes, the pan issubsequently adjusted automatically until full.

To operate the machine, power is applied to the shaft 19 by connectingthe pulley 19, which is fast on said shaft, with any suitable motor.From the shaft 19 motion is communicated to the upright shaft 15,through the medium of the gears 17 and 18, and thence to the box 13through the instrumentality of the pinion 16 and the endless rack 13,formed on the bottom of the box. As the box is reciprocated by the rackand pinon the shredded material is discharged thereinto from a suitablemachine and distributed in thin layers, one on top of the other, untilthe mass in the box is made into a suitable thickness for cakes by theaccumulated strata or layers. While the reciprocating box is gatheringthis shredded material, the lugs 36 and 36 on the arms 34 and 34* occupya position below the path of the lugs 37 and 37 on the box, and the camwheels 38 are turned through the instrumentality of the swinging cam 44attached to the box, the ratchet-wheel 41, and the pivoted pawl-arm42,which the swinging cam engages. As the cam-wheels are turned one ofthe cams 43 is a step in advance of the other, and when the moreadvanced cam reaches its highest position it engages the block 39 on thearm 34 and raises the latter sufficiently to bring the lug 36 into thepath of the lug 37. Hence the next time the box moves toward the left(see Fig. 1) the lug 37 will engage the lug 36 and actuate the arm 34sufficiently to straighten the toggles through the medium of the lever30, the yoke 31, and the bar 29, connecting the toggles. Thisstraightening of the toggles lowers the knife-belt by virtue of theconstruction hereinbefore described. The lowering of the knife-beltbrings the latter into the path of the pivoted driving-lugs 50 on thebox, and the movement of the latter actuates the knife-belt and causesthe blades thereof to enter the box 13 and cut the mass of materialtherein into cakes. The cutting is accomplished by the blades as theysuccessively assume the vertical position in the box, the arrangementbeing such that the box has reached its limit of movement toward theleft (see Fig. 1) when the knife-belt is lowered. WVhen the box hasreached its limit of movement toward the right, and the cutting of themass into c'akes is completed, the knife-belt ceases to move, and as thebox makes the return movement, or moves again toward the left, it passesfrom under the knife-belt without moving the latter, since the pivoteddriving-lugs 50 turn on their pivots as they engage the pins of thebelt, and offer no resist ance. As the box 13 moves away from theknife-belt the cakes, which are prevented by the knife-belt from movingwith the box, are dropped downward into the pan 51, and just before thebox 13 reaches its limit of movement toward the left its lug 37 engagesthe lug 36 on the arm 34 (which has been raised by its corresponding camwheel 38) and moves the lever 30 sufficiently to actuate the toggles orthrow their members from the straight to the angular position throughthe medium of the lever 54, the yoke 31, and the bar 29. This movementof the toggles raises the knife-belt out of the path of the box 13, andthe knife-belt remains idle until the box collects sufficient materialfor the next batch of cakes, and when this occurs the cam-wheel 38 willhave made another rotation, after which the operation of cutting themass into cakes and dropping the latter into the pan. will be repeated.

After the first batch of cakes is dropped into the pan the carrier orconveyer upon which the pan rests is actuated sufficiently to bring thebatch of cakes therein out from under the box, so that the next batch ofcakes will drop into the pan alongside of the first batch, and so on,the movement of the panconveyer being intermittent and at right anglesto the movement of the reciprocatingbox. The mechanism for imparting theintermittent movement to-the pan-conveyer is connected with the bar 29,and consists of the lever 57, the ratchet-arm 61, the connectingrod 60,the ratchet-wheel 64, the shafts 62 67 and their meshing gears, and abelt 69 connecting a pulley on the shaft 67 with another pulley on oneof the conveyer-shafts 8.

In order to insure the disengagement of the cakes from the knife-belt asthe box 14 moves away, the mechanism shown in Figs. 9, 10, and 1.2 maybe employed. This mechanism consists of a clearing-plate 52 ,locatedbetween the knives 21 and made fast to pins 52,which pass throughapertures formed in the links 21, and are held in place by nuts appliedto the pin extremities remote from the clearingplate. The pins 52 slidefreely in the links. These clearing-plates may be constructed to operateby gravity or by springs, as may be desired. In Figs. 10 and 12 suitablesprings 52 are shown. These springs, as shown, are two in number,andeach provided with a central coil, their extremities bearing againstthe links and the clearing-plate, respectively. The springs normallyhold the plates at their outward limit of movement. As the knifebeltenters the box, however, containing the food material the knives passthrough said material, and the plates 52 are moved upwardly, placing thesprings under tension.

Hence as the box 14 moves away from the knife-belt the recoil of thesprings will force the plates downwardly and insure the disengagement ofthe cakes from the knife-belt.
